使用密钥登陆是可以的,但是在别的机器上使用密码登陆就不行了。服务器系统版本是 Centos 7.8.2003.
尝试过以下的步骤:
root pts/1 170.3.69.2 Fri Jun 4 15:49 still logged in
root pts/1 170.3.69.2 Fri Jun 4 15:47 - 15:49 (00:01)
root pts/1 170.3.69.2 Fri Jun 4 15:46 - 15:47 (00:00)
...省略一些差不多的 ...
roo pts/0 :0 Wed Mar 24 12:23 - 12:24 (00:01)
roo pts/0 :0 Wed Mar 24 12:16 - 12:23 (00:07)
roo :0 :0 Wed Mar 24 12:10 - down (00:14)
reboot system boot 3.10.0-1127.el7. Wed Mar 24 12:00 - 12:24 (00:24)
既然使用密钥可以登陆的话,那网络问题应该排除了。实在没有办法了,有没有大佬能帮忙鉴定下问题出现在哪里?
这个是使用密钥成功能登陆的日志( ssh -v -p 22 <ip 地址>):
